The MSSD offers relatively significant performance and deserves its 4 stars. Why not five? Because I bought it to install it on a server running 24h / 24 and it quickly heats. It happens to 50 ° -52 ° C in less than an hour by inactivity and rises to 60 ° C operating (measured with lm_sensors) in a room at 18 ° - 20 ° C. It is guaranteed to operate up to 70 ° C, but I'm not one to push the hardware to its limits for a production server. He certainly very hot as it is in a small case (Shuttle slim) but it's a bit the aim of this type of SSD.
I finally removed because it was warm all my settings (again because of the narrowness of the case).
